Abstract

Abstract A high-production machine of the vertical four-slide type for intermittently advancing strip stock, severing blanks therefrom, forming the same into bearing races and welding end portions thereof together. The machine has a projecting horizontal mandrel with three work stations therealong respectively for preforming, forming, and preheating and/or welding. A cutoff anvil, transfer pins, broaching tools, and an expandable mandrel section are provided all with rear motion drive action and a welding mechanism is adapted for both preheat and weld operation adjacent the expandable mandrel section. A bearing race discharge track extends from the welding station to an induction furnace.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 167 words
The combination in a wire- or strip-forming machine of a vertical frame, four interconnected camshafts arranged in parallel pairs in a vertical plane and in a generally horizontalvertical rectangular configuration, a mandrel supported by the frame within the rectangular configuration of said camshafts and projecting generally horizontally forwardly therefrom, means for successively feeding workpieces transversely of said mandrel to a position adjacent thereto, a plurality of reciprocal tools arranged in front of said frame in a generally vertical plane within the rectangular configuration of the camshafts and in a hub-spoke configuration about said mandrel, tool-operating means including cam means on said camshafts for moving said tools toward and away from the mandrel for operation on workpieces at the mandrel, and at least three independently movable workpiece engageable devices in front of the frame and each of which has an actuating means which extends rearwardly through the frame and which is connected with cam means and driven from one of said camshafts from a position behind the frame.
Claim 2
Dependent Claim 167 words
The combination in a wire- or strip-forming machine of a vertical frame, four interconnected camshafts arranged in parallel pairs in a vertical plane and in a generally horizontalvertical rectangular configuration, a mandrel supported by the frame within the rectangular configuration of said camshafts and projecting generally horizontally forwardly therefrom, means for successively feeding workpieces transversely of said mandrel to a position adjacent thereto, a plurality of reciprocal tools arranged in front of said frame in a generally vertical plane within the rectangular configuration of the camshafts and in a hub-spoke configuration about said mandrel, tool-operating means including cam means on said camshafts for moving said tools toward and away from the mandrel for operation on workpieces at the mandrel, and at least three independently movable workpiece engageable devices in front of the frame and each of which has an actuating means which extends rearwardly through the frame and which is connected with cam means and driven from one of said camshafts from a position behind the frame.
Claim 3
Dependent Claim 32 words
The combination in a wire- or strip-forming machine as set forth in claim 1 wherein four movable workpiece engageable devices are provided in front of the frame with actuating means as aforesaid.
Claim 4
Dependent Claim 40 words
The combination in a wire- or strip-forming machine as set forth in claim 1 wherein one of said workpiece engageable devices takes the form of a tool movable longitudinally of the mandrel for operation on a workpiece at the mandrel.
Claim 5
Dependent Claim 24 words
The combination in a wire- or strip-forming machine as set forth in claim 3 wherein said tool takes the form of a broaching tool.
Claim 6
Dependent Claim 38 words
The combination in a wire- or strip-forming machine as set forth in claim 1 wherein one of said workpiece engageable devices takes the form of a mandrel part movable to effect operation on a workpiece at the mandrel.
Claim 7
Dependent Claim 40 words
The combination in a wire- or strip-forming machine as set forth in claim 5 wherein said movable mandrel part takes the form of an expansion device adapted to engage interiorly and to expand a generally circular workpiece at the mandrel.
Claim 8
Dependent Claim 42 words
The combination in a wire- or strip-forming machine as set forth in claim 6 wherein a second one of said workpiece engageable devices takes the form of a tool movable longitudinally of the mandrel for operation on a workpiece at the mandrel.
Claim 9
Dependent Claim 49 words
The combination in a wire- or strip-forming machine as set forth in claim 7 wherein a third one of said workpiece engageable devices takes the form of a movable cutoff anvil, and wherein a cutoff device is provided for operation in timed relationship with said feed means and anvil.
Claim 10
Dependent Claim 43 words
The combination in a wire or strip-forming machine as set forth in claim 8 wherein a forth work engageable device and actuating means therefor is provided in the form of a workpiece transfer device movable longitudinally of the mandrel to advance workpieces therealong.
